SHOE REPAIRING JACK Filed May l, 1931 INVENTOR. JAMES LEEDS 1 FIESI BYATTORNEY.

Patented Apr. 19, 1932 JAMES LEDDY, OF SAN FRANCISCO, CALIFORNIA SHOEREPAIRING JACK Application filed May 1,

The present invention relates generally to improvements in shoerepairing jacks and more particularly to improvements in shoe repairingjacks of lever actuated character.

The primary object of the present invention is to provide a shoerepairing jack which eliminates the strap generally used bycobblers tohold the shoes on the usual form of shoe jack.

Another object of the invention is to provide a shoe repairing last ofthe class described which includes mechanism for clamping shoes by thesoles thereof and also means for clamping the heels of womens shoes tothe last.

Still another object of the invention is to provide a shoe repairing ackwhich positively clamps the shoe in place upon the last form and holdsthe same in fixed position while the shoe is being half-soled or theheel of the shoe is being repaired.

Additional to the foregoing objects is that of providing a mechanicallyoperated shoe repairing last which is comparatively simple inconstruction and operation.

Other objects and advantages of the invention will become apparent withreference to the subjoined specification and the accompanying one sheetof drawings in which Figure 1 is a side elevation illustrating the ackin general and showing a shoe clamped in position upon the last thereof;

Figure 2 is an enlarged side elevation of the operating mechanism of thejack and showing the last in reversed positions;

Figure 3 is an edge view illustrating the jack with the shoe clamp inoperative position as in clamping a mans shoe upon the last of thedevice;

Figure 4 is a vertical sectional detail illustrating the variousoperating parts of the jack, as indicated by the line 4-4 in Figure 2;

Figure 5 is a perspective detail illustrating a womans shoe held inposition upon the last by means of an additional heel clamp carried bythe device; 7 v

Figure 6 is a sectional detail illustrating the configuration of thelast supporting spindie, as indicated by the line 6-6 in Figure 4; and

1921. Serial No. 534,177.

Figure 7 is a fragmentary detailillustrating the hingeand means fornormally urging the shoe clamping lever to inoperative position, asindicated in full lines in Figures 1 and 2-and in dottedlines in igure3.

Referring more particularly to the drawings in which the preferred formof the invention been illustrated the'numeral 10 generallydesignates theshoe repairing ack, M

The head 13 carries the working parts of the device and consists of theusual removable and reversible last 1.7 fitted upon the upper taperedend 18 of the shank 19 upon which the shoes are placed for half-solingand the like.

As indicated in Figure 1, a shoe 20 is shown clamped upon the last 19for repair purposes and is indicated as clamped to the last in thefollowing manner V Aclamp lever 21 arranged transversely of the last 17and pivoted or hinged at the point 22, which hinge is carried by aslidable collar 23, arranged to slide upon the shank 19, carries saidclamp lever upwardly and clamps the shoe on the last, by, and throughmeans hereinafter described.

An actuating lever 24-, pivoted at the point 25 to the collar 23 andhaving an arcuate slot 26 arranged in the segment 27 thereof, which slot26 engages a pin 28 carried by a fixed collar 29, causes the upwardmovement of the slidablecollar v23 upon the shank 19.

This upward movement of the slidable collar 23 is'due to the fact thatthe pivot point 25 is eccentrically arranged relative to the arcuateslot 26 formed in the segment 27, which causes the clamp 21 to be firstraised upwardly and then brought downwardly to engage the shoe sole andhold the shoe in a firm clamped position upon the last.

The collar 23 also carries an upright bracket 30, which bracket haspivotally supported at its upper end a heel clamp 31 having a forked end32 adapted to grip and hold the heels .33 of womens shoes, a fragment ofwhich is shown on the last 17 in Figure 5.

The heel clamp 31 is manually controlled and normally rests in theposition shown in Figures 1 and 2 as also does the clamp lever 21, asindicated in Figure 3, a handle 34: being attached to said lever 21 toprovide means for the manual swinging of the same from inoperative tooperative positions.

A heavy coil spring 35 is mounted upon the shank 19 between the slidablecollar 23 and a fixed collar 36, said spring tending to normally urgethe actuating lever 24 downwardly to assist the operator in drawing theclamp 21 downwardly upon the shoe sole.

What I claim and desire to secure by Letters Patent of the United Statesis the following 1. A shoe repairing jack of the class describedcomprising an operating head including a fixed shank having a lastmounted thereon, a slidable collar upon said shank, shoe clamping leverscarried by said collar and eccentric means associated with the collarand adapted to actuate said clamping levers.

2. A shoe repairing jack of the class described comprising an operatinghead e1nbodying a fixed shank having a shoe last associated therewith, aslidable collar mounted upon said shank, shoe clamping levers pivotallycarried by the collar, and a segment eccentrically mounted upon thecollar and adapted to actuate said clamps.

3. A shoe repairing jack of the class described as claimed in claim 2and including spring means cooperating with the slidable collar to urgethe clamps to shoe clamping positions.

l. A shoe repairing jack of the class described comprising, incombination, an operating head embodyin a fixed shank having a shoe lastassociated therewith, a slidable collar mounted upon said shank, shoeclamping levers pivotally mounted upon the collar, and segmentseccentrically mounted relative to the collar and adapted to raise thesame and carry the clamping levers upwardly and then downwardly to clampthe shoe fixedly upon the last.

In testimony whereof I hereunto ailix my signature.
